Troubleshooting
If the lift does not work properly, the reason for this might be quite simple. Please check
the lift for the potential reasons mentioned on the following pages. If the cause of
trouble cannot be found, please call the technical service.
Problem: Motor does not start!
Potential causes:
-
Main switch is not engaged
- The feed line is cut
- Power failure
- Thermofuse in the motor is activ (let it cool down approx. 10
min)
Problem: Motor starts, lift does not lifting!
Potential causes:
-
The vehicle is too heavy
- Level of the oil is too low
- The emergency lowering screws are not closed
- The hydraulic hoses are dirty
- The cylinder jams
Problem: The lift does not lowered!
Potential causes:
-
The lift is standing on a obstacle
- The hydraulic valve is defective
- The button „lowering“ is not pressed
6.1 Driving on an obstacle
If the lift is driven on an obstacle the lift stopps mechanically. Press the button „lifting“
until the obstacle can be removed.
6.2 Emergency lowering in case of power failure or defective valve
In this case of power failure or defective valve, the hydraulic valve of the lift will not open
any more. Therefore the lift can not be lowered. In this case there is the possibility to open
the hydraulic valve manually and to lower the lift to it´s lowest position, so the vehicle can
be driven off.
